5 is a conceptual diagram illustrating a method of providing goods information according to an embodiment of the present invention.

5 illustrates how merchandise information is provided to a viewer via display 500 when video content is played on the viewer's display 500 in real time (e.g., real-time terrestrial, real-time cable, etc.).

For example, a viewer may be provided with merchandise information related to video content transmitted via airwaves. For example, if a viewer wishes to be provided with product information related to a specific screen of video content transmitted to the display 500 in real time, it is possible to use a specific button (e.g., a pause button) A temporary screen stop can be performed. For example, when the viewer presses the pause button, the display 500 can store the frame corresponding to the still picture in a memory and provide it to the viewer.

The display 500 may transmit information on the paused screen to the product information providing unit 550. The information on the paused screen may be, for example, identifier information of a frame corresponding to a paused screen, identifier information of video contents including a paused screen, and the like. The goods information providing unit 550 may provide the goods information corresponding to the video contents.

Alternatively, another network device (for example, a home PC) may display a pause screen from the display 500 without sending the information about the screen in which the display 500 is directly paused to the product information providing unit 550 And may transmit the information to the product information providing unit 550.

The goods information providing unit 550 may receive the information on the paused screen and transmit the goods information related to the paused screen to the display 500. [ Or the product information providing unit 550 may further transmit the product information related to the partial screen reproduced before the paused screen to the display 500. [ For example, the product information providing unit 550 can search for product information that is matched based on the identifier of the content corresponding to the paused screen, the identifier information of the frame, and displays the searched product information on the display 500 Lt; / RTI >

The display 500 can receive the product information from the product information providing unit 550 and reproduce it. The product information may include advertisements for physical goods, human goods (services, events, etc.) as described above.

[ The product information providing unit 550 may transmit additional advertisement information (specific product description information, payment information, and the like) related to the selected specific product to the display 500.

The display 500 may not use the full screen of the display 500 to provide product information to the user, but may use only some screens. For example, a screen for providing product information to a user is limited to a portion of a screen on the upper right side of the entire screen, and an over-the-air broadcast can be provided to a user in real time through the remaining screen.

5, a method of providing product information related to paused video content to a viewer is disclosed, but the same advertisement may be continuously provided through metadata in which video content and an advertisement image are mapped. For example, in the case of 8 o'clock to 10 o'clock in the morning, the providing target of the goods information may be set as the housewife. In this case, the product information providing system can provide not only the product information related to the video contents but also the product information that targets the housewife as the advertisement in relation to the video contents provided at 8:00 am to 10:00 am.

6 is a conceptual diagram illustrating a goods information providing system according to an embodiment of the present invention.

Referring to FIG. 6, the product information providing system may analyze the image on the video content and provide the product information to the viewer.

In the above-described embodiment, only the product information about the predetermined product on the video content can be provided. However, according to the embodiment of the present invention, the product information on the arbitrary product as well as the predetermined product on the video content may be provided.

For example, it may be assumed that a viewer wants to acquire product information for a specific product while watching the video content. In this case, the viewer can perform screen capture of the entire image including the product image. The screen-captured product image may be transmitted from the display 600 to the viewer's communication device (e.g., smartphone) 620. The moving picture information for a certain period may be transmitted to the communication device 620 after the screen capture button is pressed rather than the screen captured image.

The communication device 620 may separate the product image and the background image from the screen-captured image. After the product image and the background image are separated from the screen-captured image, the product image can be displayed on the screen-captured image based on a separate identification image. For example, an identification image, such as an outline, an outline, a highlight, etc., is combined with a product image and displayed on a screen-captured image so that the product image can be identified separately from the background image.

The viewer can select at least one product image among the product images to which the identification image is added based on the interface such as the touch screen on the communication device 620. [ The product image selected by the viewer can be expressed by the term selected product image. An image-based product information search can be performed based on the selected product image. Specifically, the communication device 620 can transmit the image information of the product (object) to the image analysis server 640, and the image analysis server 640 can receive the product information corresponding to the image information of the product (Product name, product dealer, product price, etc.).

The image analysis server 640 may transmit the product information to the viewer's communication device 620. [

6, a method of receiving product information from an image analysis server 640 through a viewer's communication device 620 has been described. However, it is also possible to transmit the image information of the goods directly to the image analysis server 640 on the display 600 without passing through the communication device 620 as an intermediary and to transmit the image of the goods through the display 600 or the viewer's communication device 620 Information on products corresponding to information may be provided, and such embodiments may also be included in the scope of the present invention. In the embodiment of the present invention, a method of transmitting image information of a product to the image analysis server 640 via the communication device 620 as an intermediary for the sake of explanation will be described.

7 is a flowchart illustrating an operation of an image analysis server according to an embodiment of the present invention.

7, a method of acquiring product information based on image information (or product image) of a product received by the image analysis server will be described.

As described above, the communication device can transmit the product image to the image analysis server on the screen-captured image. The image analysis server can obtain the product information through analysis of the image of the product.

Referring to FIG. 7, the image analysis server may preferentially analyze the outline of the product image based on the image of the product (step S700).

The image analysis server can analyze the outline of the product image through edge analysis. For example, the image analysis server can analyze the outline of the object based on the change of luminance, saturation-related data of the pixel with respect to the product image. The image analysis server can further utilize the information on the category of the product in analyzing the outline of the object.

The image analysis server can generate the first product outline information by analyzing the outline of the product based on the change of the luminance and chroma related data of the pixel. In addition, the image analysis server may generate the second product outline information by analyzing the outline of the product based on the information on the category of the product.

The image analysis server may roughly determine the category of the goods to generate the second goods outline information. For example, if the product image is an image for a handbag, the image analysis server can preferentially obtain information that the category of the product corresponds to a handbag through a rough image analysis. The image analysis server may obtain information on the category of the goods and obtain the second goods outline information based on various images (e.g., various images for the handbag) for the goods category.

The portion corresponding to the intersection of the first product outline information and the second product outline information can be determined as the final outline information of the product.

After determining the final outline information of the product, the product detail image information may be analyzed (step S720).

The detail image information of the product can be performed through analysis of corner information and edge information of the product image. Corner information and edge information in the product image can be determined based on the directionality of the image change. The product detail image information may include color information as well as corner information and edge information of the product image. A method of analyzing corner information and edge information of a product image will be described later.

The image analysis server can calculate the matching degree by comparing the analyzed product detail image information with the detail image information of various products located in the image analysis server.

* The image analysis server can determine the image having the highest matching degree and search for the product information (goods dealer, product image of various angles, product price, etc.) associated with the image having the highest matching degree (step S740) .

The image analysis server may deliver product information associated with the image with the highest matching degree of discovery to a display or viewer's communication device.

8 is a conceptual diagram illustrating a method of analyzing product detail image information according to an embodiment of the present invention.

The search window 800 may be moved within the final contour of the article to obtain directionality of the image information change. The search window 800 can obtain surrounding pixel information while moving at specific angles (for example, one pixel unit) up or down, left or right or at a specific angle with a specific position as a reference point. The search method of the search window 800 may be expressed in terms of the peripheral pixel information acquisition procedure of the search window 800.

The size of the search window 800 can be set according to the accuracy of the analysis of the product detail image information.

8, if the position of the search window 800 is not the position of the corner and the edge, the neighboring pixel information obtained based on the neighboring pixel information obtaining procedure of the search window 800 has no direction of change .

8, if the search window 800 is located at the edge position, the neighboring pixel information obtained based on the neighboring pixel information obtaining procedure of the window may have one change direction. In particular, pixels having different properties with respect to the edge may be located on the search window 800. In the case of the interruption of Fig. 8, when the search window 800 is moved from side to side, pixels having different properties around the edge in the vertical direction can be searched. In this case, It is possible to judge that the edge of < RTI ID = 0.0 >

 8, if the search window 800 exists at a corner, the neighboring pixel information obtained based on the neighboring pixel information obtaining procedure of the search window 800 has a plurality of directions of change . Specifically, a pixel having a plurality of change orientations with respect to the corner may be located on the search window 800. In the case of the bottom of FIG. 8, when the search window 800 moves in the left and right direction, pixels having different properties around the vertical edges can be searched. In addition, when the search window 800 moves in the vertical direction, pixels having different properties can be searched around the edges in the horizontal direction.

In this case, it can be determined that the edge is positioned in the upward direction and the left-right direction in the portion where the search window 800 is located, and it can be determined that the corner exists at the point where the edge in the up-down direction and the left-right direction meet.
